How It Works
Enter any stock ticker symbol (e.g., AAPL, TSLA, MSFT) to view real time price data and an interactive candlestick chart. The stock chart tool fetches data from Yahoo Finance through a secure server side proxy: your browser never connects directly to external services, keeping your queries private. Search AAPL, MSFT, or any US ticker to load OHLC candlesticks with volume. Switch from 1 day intraday to 5 year monthly views depending on whether you trade short term swings or review long term trends. Weekly bars reduce noise for swing traders. Monthly bars suit multi year retirement portfolio reviews of core holdings. Use the shareable URL path to return to the same symbol without retyping. International listings often need an exchange suffix such as .L for London or .TO for Toronto so Yahoo resolves the correct instrument. Earnings days often produce wide range daily bars worth reviewing on the day after each quarterly report when you size new entries. Search AAPL, MSFT, or any US ticker to load OHLC candlesticks with volume. Switch from 1 day intraday to 5 year monthly views depending on whether you trade short term swings or review long term trends.
The chart supports multiple time ranges: from a single day with 5 minute candles to 5 year views with monthly bars. Three moving average overlays (SMA 20, 50, 200) help you identify trends and potential support or resistance levels. Volume bars at the bottom show trading activity for each period. Toggle SMA 20, 50, and 200 overlays to spot golden crosses and death crosses. Price above rising SMA 200 often signals long term uptrend in trend following frameworks. Crosshair tooltips show exact open, high, low, close, and volume for any bar. Compare day range and 52 week range metrics beside the chart when sizing position risk or setting trailing stop levels from recent swing highs. Toggle SMA 20, 50, and 200 overlays to spot golden crosses and death crosses. Price above rising SMA 200 often signals long term uptrend in trend following frameworks.
